2y Claims.

The main object of this invention is to provide an apparatus for attaching envelopes and labels to wood, paper, and metallic boXes, as well as to receptacles made of fabric, leather and other materials. I

The second object is to attach the envelope or label to the package in a manner to consume the minimum amount of time, save adhesive, and not apply it to areas to which the envelope is not to be attached.

Before entering into an explanation of this invention, it must be understood that of all the various devices intended for this purpose, the glue pot has thus far proved most uniformly satisfactory for all kinds of receptacles, the principal drawback being in the loss of time, waste of glue, and the smeary appearance which such fastening produces. It is therefore my ob.- ject to retain the advantages of the glue pot, and eliminate the disadvantages.

I accomplish this and other objects in the manner set forth in the following specification, as illustrated in the accompanying drawing, in which:

Fig. 1 is a plan of the device.

Fig. 2 is a front elevation of the device.

Fig. 3 is a vertical section taken along the line 3--3 in Fig. 1.

Fig. 4 is a bottom view.

Fig. 5 is an inverted vertical section through the device, taken along the line 5-5 in Fig. ll.

Fig. 6 is a perspective view of a representative form of package showing the type of adhesive application made thereon.

Fig. '7 is a front elevation of a representative form of envelope attached by the adhesive.

Fig. 8 is an enlarged section through the pet cock and check valve.

Fig. 9 is a transverse section taken along the line 9--9 in Fig. 3.

Similar numerals refer to throughout the several views.

Referring in detail to the drawing, there is shown the container consisting of the sides II) and closed top I I, in one corner of which is disposed a leg I2, and in the other corner of which is disposed a pet cock I3 which forms a second leg whose valve M controls the ow of air into said container and contains a ball check valve I5 adapted to prevent the escape of adhesive I6 from the container when in an inverted position as shown in Fig. 5.

A handle I1 is also provided across the end I I. At the opposite end of the container is secured a similar parts closure I8 of wood or any other suitable material having its underside I9 disposed a short distance from the lower edges 20 of the sides I.

A groove 2I is formed about the perimeter of the face I9 near its outer edge. The groove 2i communicates with the interior of the container through the closure I8 by means of the holes 22.

Secured to the face I9 by means of the tacks 23, and also secured to the member I8 through the side walls IU by means of the tacks 24, is a rectangular frame of absorbent material 25. Adhesive I6 is admitted into the interior of the container through the iiller hole 26 from which the cap 21 has been removed.

The operation of the device is as follows:

Assuming that a quantity of glue is disposed within the container and it is desired to aiix a label or envelope to a package, it is only necessary to set the device as shown in Fig. 2 which will permit glue to pass downwardly through the openings 22 from which it passes around the groove 2| and saturates the material 25. The device is then grasped by the handle I'I and placed against the package 28, leaving thereon an imprint 29 of moist adhesive in the form of a rectangular area somewhat smaller than is the area of the envelope or label 30 to be attached thereto.

Obviously, no advantage is gained from applying adhesive to the middle portion of the envelope or label 30, nor would any be gained by applying it to areas outside of the bounds of the label.

It can be seen that the application of the glue is not only neatly and quickly performed, but it also conserves the adhesive and assures the uniform application thereof.

When not in use, the device should be inverted as shown in Fig. 5.

To control the rate of flow of the adhesive, it is only necessary to manipulate the valve I4. It can be seen that once the position of the valve I4 is determined, it need not be changed every time the device is set down since the ball check valve I5 will prevent the escape of the adhesive from the pet cock I3.

I claim:

l. A device of the class described consisting of a closed reservoir having a wooden end, a hcllow square of absorbent material secured against said wooden end, a plugged iiller opening within said hollow square, said wooden end having a plurality of openings therein communicating between said absorbent material and the interior of the reservoir, a D-shaped handle on the opposite end of said reservoir, together with leg members also projecting from the handled end of said reservoir cooperating with said D-shaped handle to permit said reservoir to stand in an inverted position, one of said legs having an air inlet opening extending therethrough, a needle valve for controlling the flow of air through said opening for the purpose of controlling the dispensing of adhesive.

2. A device of the class described consisting of a container having closed upright sides, and a closed top, said top having a handle projecting upwardly therefrom and leg means for holding same in an inverted position. said top also having adjustable air inlet valve including a ball check adapted to close against outward movement of adhesive when the device is inverted, a bottom for said container extending beyond the under edge of the container sides, a rectangular absorbent pad having an opening Whose inner edge is attached to the bottom of the container and whose outer edge is attached to the sides of the container, said bottom having openings therein communicating between the interior of the container and the absorbent pad.
